Why do old 9000's (about 4 years and older) have a syrupy smell that comes from the vents? It has happened on two of my familly's saab 9000's a 1992 and a 1995. It is a sweet sugar sypup smell. If you could explain that would be great. Or if your car does the same thing. Write me an email. thanks(posted 9255 days ago)
